How To Downgrade 12.3.2 Without Losing Data

Apple releases iOS 12

A Chinese security researcher recently detailed Chaos exploit for iOS 12.1.1 and lower that will work on all not-A12 devices like the iPhone X, iPhone 8, and iPhone 7. While he did non release the exploit code, it has given hopes to the jailbreak community of a possible iOS 12 – iOS 12.1.two jailbreak tool being on the horizon. So, if yous have already updated to iOS 12.i.3, it is strongly recommended that you lot downgrade back to iOS 12.1.i – iOS 12.ane.2 if yous want to jailbreak your iPhone or iPad.

Right at present, it is unclear if the Chaos exploit works with iOS 12.one.ii or non. Thus, it is recommended that you downgrade dorsum to iOS 12.1.1 to be on the condom side. Apple is still signing iOS 12.ane.1 and iOS 12.1.2 but with iOS 12.1.three released, I expect the iOS 12.1.ane signing window to close inside the next 24-48 hours.

Update (Jan 31, 2019):

Security researcher Brandon Azad has released an iOS 12 – iOS 12.1.ii kernel exploit for iPhones and iPads, and so it looks similar there is a possibility of the much awaited iOS 12 jailbreak tool that supports iOS 12.i.2.
